Transperformance 18: Letters and Numbers was held August 26th, 2008 at the Pines Theater in Look Park, Northampton.

The 18th annual fundraising event was jointly presented by the Northampton Arts Council and the PTOs of the four Northampton elementary schools, J.F.K. Middle School and Northampton High School.

The Northampton Arts Council, who also shared in the profits from the past Transperformances, has been able to use the money raised to provide a second round of funding for local artists. These rounds of funding support the work of many, many artists and performing groups.

Transperformance 18: Letters and Numbers included many local bands performing in the guise of well-known performers, such as the Drunk Stuntment as the J. Geils Band, The Florence Community Band as the Boston Symphony Orchestra, MC Higgins & Co as R.E.M. and The Primate Fiasco as Guns N' Roses.
